The present patent document claims priority and contains subject matter related to Japanese Patent Application No. 2004-049178 filed in the Japanese Patent Office on Feb. 25, 2004 and the entire contents of which are hereby incorporated herein by reference.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a multi-function image forming apparatus connected with a network and capable of transmitting and receiving a variety of data to and from network terminal apparatuses using a plurality of communication protocols.

2. Discussion of the Background Art

Recently, a network communication system including a so-called multi-function image forming apparatus has been developed. The multi-function image forming apparatus is capable of communicating with terminal apparatuses in the system using a variety of communication protocols.

A wide variety of application services are provided in such a multi-function image forming apparatus connected with the network communication system. For example, a so-called scan-to-email service provides a service to scan an original document with an image read device of the multi-function image forming apparatus and to transmit image data of the original document to a designated mail address using email. An email print service provides a service to print out body information of a received email and an image of an attached file of the received email. A facsimile transfer service provides a service to transfer body information of a received email and an image of an attached file of the received email to a designated facsimile apparatus.

In such a multi-function image forming apparatus, however, when transmitting image data of an original document, that has been obtained by scanning the original document, with email using the above-described scan-to-email service, an address, a subject, and the body of an email must be manually input by the user, which is troublesome.

SUMMARY OF THE INVENTION

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Referring now to the drawings, wherein like reference numerals designate identical or corresponding parts throughout the several views.

In the following description, words, idioms, or abbreviations representing product names or specific image formats are included. Some of them are registered trademarks or trademarks of respective manufactures, organizations or individuals; however, annotation thereof might be omitted in cases in which they are generally or commonly used in technical fields to which the present invention is applied.

The description of the preferred embodiments is made taking as an example a digital color multi-function image forming apparatus in which a copier function, a facsimile function, a print function, a scanner function, an image storage function, an image distribution function, etc, are integrated.

FIG. 1 schematically illustrates a construction of a network communication system including a digital color multi-function apparatus 1 according to an embodiment of the present invention.

As illustrated in FIG. 1, the digital color multi-function apparatus 1 is connected with a server computer 3 and a plurality of client computers 4 via a local area network (LAN) 2 as an example of a communication network. The server computer 3 and the plurality of client computers 4 perform various types of information processing, respectively. The server computer 3 supports, for example, FTP (file transfer protocol) and HTTP (hyper text transfer protocol), and realizes functions of a Web server and a DNS (domain name service) server.

That is, a network environment is realized in the network communication system such that image process functions of the digital color multi-function apparatus 1, such as, the scanner function (an image input function), the print function (an image output function), image storage function, etc., are shared on the local area network 2.

The communication network system is connected with the Internet 6 via a communication control unit 5 to communicate with the outer environment.

The communication control unit 5 may be realized with a router, a switching apparatus, a modem, or a DSL modem, that is at least capable of TCP/IP (transmission control/Internet protocol) communication. The local area network 2 may be a wired network using, for example, optical fiber cables, or a wireless network using, for example, infrared rays, radio waves, etc.

FIG. 2 is a schematic perspective view of the digital color multi-function apparatus 1. FIG. 3 is a block diagram illustrating electrical connections of respective parts of the digital color multi-function apparatus 1.

As illustrated in FIG. 2, in the digital color multi-function apparatus 1, an image read device 8 configured to read an image of an original document is arranged on a print device 7 configured to form an image on a medium such as a transfer sheet.

An operation panel P configured to display messages for the operator and to allow various inputting by the operator, such as setting of a function, etc., is provided on an outer surface of the image read device 8.

Further, an external media input/output device 9 is provided on a lower part of the operation panel P with an insertion opening thereof exposed to allow insertion of a storage medium M, such as an optical disk, a flexible disk, etc. The external media input/output device 9 is configured to read program codes, image data, etc., stored in the storage medium M, and to write program codes, image data, etc. to the storage medium M.

The digital color multi-function apparatus 1 includes, as illustrated in FIG. 3, an image process unit A and an information process unit B. The image process unit A includes the print device 7 and the image read device 8, and the information process unit B includes the operation panel P and the external media input/output device 9.

First, the image process unit A is described.

The image process unit A includes an image process control unit 10 configured to control overall image processing at the image process unit A. The image process unit A is connected with a print control unit 11 configured to control the print device 7 and an image read control unit 12 configured to control the image read unit 8.

The print control unit 11 outputs a print instruction including image data to the print device 7 and causes the print device 7 to form an image on a medium such as a transfer sheet according to control of the image process control unit 10. The print device 7 is capable of forming a full color image on the medium. The print device 7 may use any of electrophotography, ink jet printing, sublimation type thermal transfer printing, silver film photography, direct thermal recording, fusion type thermal transfer printing, etc.

The image read control unit 12 drives the image read device 8 according to control of the image process control unit 10. A reflected light from a surface of an original document is condensed onto a light receive element, such as a CCD (charge coupled device), and thereby image data of an image of the original document is obtained. The image data is then converted, by performing analog to digital conversion thereto, to digital image data of R (red), G (green), and B (blue), each in 8 bits.

The image process unit 10 includes a CPU (central processing unit) 13 serving as a main processor, a SDRAM (synchronous dynamic random access memory) 14 for temporarily storing image data obtained by the image read device 8, a ROM (read only memory) 15 storing a control program, etc., and a NVRAM (non-volatile random access memory) 16 capable of holding data even when the power has been turned off and storing system setting information, system logging information, etc. The CPU 13, the SDRAM 14, the ROM 15, and the NVRAM are connected with each other by a bus.

The image process unit 10 is connected with a HDD (hard disk drive) 17 serving as a storage device for storing a large volume of image data, job history, etc., a LAN (local area network) control unit 18 connecting the image process unit A with the LAN 2 via a HUB 19 serving as a line concentrator of an internal LAN, and a facsimile control unit 20 configured to control facsimile communication.

The facsimile control unit 20 is connected with a PBX (private branch exchange) 22 connecting to a PSTN (public switched telephone network) 21 (see FIG. 1), so that the digital color multi-function apparatus 1 can communicate with a remote facsimile apparatus via the PSTN 21.

The image process control unit 10 is connected with a display control unit 23 and an operation input control unit 24. Under control of the image process control unit 10, the display control unit 23 outputs an image display control signal to the information process unit B via a communication cable 26 connected with a control panel I/F (interface) 25, and controls displaying of an image at the operation panel P of the information process unit B.

The operation input control unit 24 inputs, under control of the image process control unit 10, an input control signal responding to setting of a function input by the operator through the operation panel P of the information process unit B, via the communication cable 26 connected with the control panel I/F 25.

Thus, the image process unit A is configured to be capable of directly monitoring the operation panel P of the information process unit B via the communication cable 26. That is, the image process unit A is enabled to utilize the operation panel P of the information process unit B by connecting the image process unit A with the information process unit B via the communication cable 26.

Thus, the display control unit 23 and the operation input control unit 24 of the image process unit A are operated in a state of being connected with the operation panel P.

With the above-described configuration, the image process unit A analyzes print data as image information and a print instruction command from the outside (the server computer 3, the client computers 4, facsimile apparatuses, etc.), bitmaps the print data into output image data, and analyzes a print mode based on the print instruction command to determine an operation. The print data and the command are received via the LAN control unit 18 or the facsimile control unit 20.

The image process unit A is configured to transfer data stored in the SDRAM 14 and the HDD 17, such as print data, data read from an original document, output image data of the print data and the data read from an original document, and compressed data of these data, to external apparatuses (such as the server computer 3, the client computers 4, facsimile apparatuses, etc.).

The image process unit A is configured to transfer image data read with the image read device 8 to the image process control unit 10, to correct signal deterioration caused in an optical system and in conversion to digital signals, and to write the image data into the SDRAM 14. The image data stored in the SDRAM 14 is converted to output image data by the print control unit 11 and is output to the print device 7.

Now, the information process unit B including the operation panel P is described.

The information process unit B is configured like a microcomputer controlled by a standard OS (operating system) used in personal computers. The information process unit B includes a CPU 31 serving as a main processor. The CPU 31 is connected by a bus with a memory unit 32, which is constituted by a RAM serving as a working area of the CPU 31 and a ROM storing a starter program, etc., and a storage device control unit 35 configured to control inputting and outputting of data to and from a storage device 34. The storage device 34 may be constituted by an HDD, etc., and stores the OS and application programs.

The CPU 31 is connected with a LAN control unit 33 serving as a communication interface for connecting the information process unit B with the LAN 2 via the HUB 19. An IP address assigned to the LAN control unit 33 as a network address is different from the one assigned to the LAN control unit 18 of the image process unit A. That is, two IP addresses are assigned to the digital color multi-function apparatus 1.

Thus, the image process unit A and the information process unit B are individually connected with the LAN 2, so that data communication is possible between the image process unit A and the information process unit B.

Because the digital color multi-function apparatus 1 is connected with the LAN 2 via the HUB 19, it looks as if only one IP address is assigned to the digital color multi-function apparatus 1. Thereby, handling of a wire connection is facilitated and a deterioration in the appearance is avoided.

The CPU 31 is further connected with a display control unit 36 and an operation input control unit 37, which are configured to control the operation panel P. FIG. 4 is a plan view of the operation panel P.

As illustrated in FIG. 4, the operation panel P includes a display device 40 constituted by, for example, a LCD (liquid crystal display), and an operation input device 41. The operation input device 41 includes a touch panel 41a of an ultrasonic sound wave method, etc., which is laminated on a surface of the display device 40, and a keyboard 41b having a plurality of keys.

The keyboard 41b is provided with a start key, which, by being depressed, starts reading an image to obtain image data of the image, ten keys, which, by being depressed, input a numerical value, a read condition setting key, which, by being depressed, sets a read condition, a clear/stop key, etc.

Thus, the display control unit 36 outputs an image display control signal to the display device 40 via a control panel I/F 38 and causes the display device 40 to display a predetermined content according to the image display control signal. On the other hand, the operation input control unit 37 receives from an operation input device 41 via the control panel I/F 38 an input control signal corresponding to setting of a function and inputs by the operator at the operation input device 41. The CPU 31 is connected with a control panel communication unit 39, which is connected with the control panel I/F 25 of the image process unit A via the communication cable 26.

The control panel communication unit 39 receives an image display control signal output from the image process unit A, and transfers an input control signal from the operation panel P corresponding to setting of a function and inputs by the operator at the operation panel P to the image process unit A.

The image display control signal from the image process unit A, which has been received by the control panel communication unit 39, is output, after having been converted for use at the display device 40 of the operation panel P, to the display control unit 36. An input control signal from the operation panel P, corresponding to setting of a function and inputs by the operator at the operation panel P, is input, after having been converted to a format corresponding to a specification at the image process unit A, to the control panel communication unit 39, details of which will be described later.

As described above, the OS and the application programs executed by the CPU 31 are stored in the storage device 34, so that the storage device 34 functions as a storage medium storing an application program.

In the digital color multi-function apparatus 1, when the power is turned on, the CPU 31 activates the starter program in the memory unit 32, reads in the OS to the RAM of the memory unit 32 from the storage device 34, and activates the OS. The OS causes a program to be activated, reads in information, and stores the information, in response to an operation by the operator. The family of Windows (registered trademark) is well known among various operating systems. A program that operates under an OS is called an application program. An OS similar to those used in information processing apparatuses (i.e., the server computer 3, the client computers 4, etc.), that is, a standard OS (e.g., Windows, etc.), is used for the OS of the information process unit B.

As described above, the external media input/output device 9 is mounted to the digital color multi-function apparatus 1. The external media input/output device 9 is controlled by an input/output device control unit 42, which is connected with the CPU 31 by the bus. The external media input/output device 9 reads out program codes (of the OS, device drivers, application programs, etc.), image data, etc. stored in the record medium M and writes program codes, image data, etc. into the record medium M. The record medium M may be a FD (flexible disk), a HD (hard disk), an optical disk (CD-ROM, CD-R, CD-RW, DVD-ROM, DVDRAM, DVD−R, DVD+R, DVD−RW, DVD+RW, etc.), an MO (magnetic optical disk), a semiconductor medium, or the like. The external media input/output device 9 may be a FDD (flexible disk drive) device, an optical disk drive device, an MO drive device, or a media drive device, or the like.

Thus, the application programs stored in the storage device 34 may be the ones that are stored in the record medium M and that have been read out from the record medium M and installed to the storage device 34. That is, the record medium M may serve as a storage medium for storing an application program. Further, an application program may be obtained from the outside via the Internet 6 and the LAN 2 to be installed into the storage device 34.

The input/output device control unit 42 is connected with an interface unit 43, which includes a variety of interfaces, such as USB, IEEE1394, SCSI, etc., so that a variety of apparatuses (digital cameras, etc.) may be connected with the digital color multi-function apparatus I via the interface unit 43.

Now, a characteristic process executed in the digital color multi-function apparatus I is described.

The digital color multi-function apparatus I is configured such that the image process unit A and the information process unit B can perform different processes independently from each other. For example, it is possible that while the image process unit A is performing a process of reading an image, the information process unit B can receive an email.

Further, the digital color multi-function apparatus I is configured such that each function of the image process unit A can be used by a program operating at the information process part B and a result of using the function of the image process unit A can be a processing object at the information process unit B.

For example, when obtaining a text document by processing image data of an image of a document, that has been obtained with the image read device 8 of the image process unit A, with character recognition software, it is conceivable to transmit the image data to an external computer (e.g., a PC), in which character recognition software is installed, so that the image data is processed at the external computer, or to install character recognition software, that is operable under control of the image process control unit 1 0, to the image process unit A.

Here, if the image process unit B is tailored to image processing, it is necessary to develop specific character recognition software that is operable at the image process unit B, and if the image process unit B is configured such that general-purpose character recognition software can be installed and operated, it is inevitable that the overall performance of image processing at the image process unit B is decreased.

To solve the above-described problem, in the digital color multi-function apparatus 1, a commercially available general-purpose operating system (OS) is used in the information process unit B, so that general purpose character recognition software can be operated at the information process unit B without being affected by an operation of the image process unit A, and a program operating at the information process unit B is constituted by combining process modules illustrated in FIG. 5, so that each function of the image process unit A can be used by the program operating at the information process unit B.

FIG. 5 is a block diagram illustrating the process modules of the digital color multi-function apparatus 1.

The image process unit A includes an image process control system 51, which includes control program modules for executing the image process functions of the digital color multi-function apparatus 1 (such as the scanner function, the print function, the image storage function, etc.), and a network support function module 52, which enables the image process functions of the digital color multi-function apparatus 1 (which are executed at the image process control system 51) to be used via the network (i.e., the LAN 2). The image process unit A further includes a TCP/IP 53, which can be accessed only from the image process unit B via the LAN 2.

The network support function module 52 is configured to activate a corresponding program module of the image process control system 51 when the TCP/IP 53, which always monitors access from the network (the LAN 2), has detected a connection request relative to a port number.

For example, when a connection request relative to a port number 1002 has been received, a control program module executing the facsimile reception function is activated at the image process control system 51. The activated module is operated in cooperation with a process request from the connection request originator, and sends back a necessary response to the connection request originator.

The network support function module 52 cannot be used from devices of the image process unit A.

Next, a feature of the process modules of the information process unit B is described.

A scan-to-email application 54 serving as an email transmission device of the present invention extracts image data of an address area, a subject area, and a body area of an original document from image data of the original document, performs character recognition relative to the extracted image data of an address area, a subject area, and a body area of the original document with an OCR (optical character recognition) engine 57 to obtain character strings of the address area, the subject area, and the body area of the original document, sets the obtained character strings of the address area, the subject area, and the body area of the original document as an address, a subject, and a body of an email, and transmits the email while attaching the image data of the original document to the body of the email.

Each application of the information process unit B is operated under management of an operating system (OS) 58. As described above, a commercially available general-purpose operating system, such as Windows (registered trademark), etc., is used for the OS 58.

Further, each application of the information process unit B can use functions provided by the OS 58. That is, in a program executing the application, a necessary process is executed by invoking each of the functions provided by the OS 58 as a software module. For example, a TCP/IP control module 59 executes a function of communicating with terminal apparatuses connected by the TCP/IP 53, which is provided in the OS 58.

Furthermore, each application of the information process unit B can use independent software installed for use by other applications. For example, the OCR engine 57, which performs character recognition only, is not operated independently, and is used as a module of other software.

Thus, the information process unit B is configured such that each application operates under management of the OS 58, so that an application (such as the scan-to-email application 54) can be developed using a function or a combination of functions of other applications.

As described above, in the digital color multi-function apparatus 1, the image process unit A configured to realize the standard image process functions and the information process unit B configured to execute application software are provided, and the image process unit A and the information process unit B are internally connected with each other via the network (LAN 2) by the TCP/IP 53. With this configuration, physical connection of the image process unit A and the information process unit B is realized and data communication between the image process unit A and the information process unit B is enabled.

Next, a method of enabling application software operating at the information process unit B to use a function of the image process unit A is described.

For example, in the scan-to-email application 54, image data as an object for character recognition is the image data read from the image read device 8 managed at the image process unit A.

Here, to instruct the image read device 8 to perform an operation of reading an image, a TCP/IP connection request is transmitted to the image process unit A while designating a port number 1001. Further, at this time, data indicating the content of a requested process is transmitted at the same time as a data stream. Here, the port number 1001 designates, for example, the function that the image read device 8 reads an image and transfers image data of the image to the information process unit B with an arbitrary file name attached thereto. The content of the process of each function is defined in advance, and a port number is assigned to each function so that the function can be used individually.

Thus, using each function of the image process unit A from the scan-to-email application 54 is enabled.

Of course any communication protocol other than TCP/IP may also be used.

The digital color multi-function apparatus I may be provided with, in addition to the standard image process functions described above (i.e., the copier function, the scanner function, the print function, the facsimile function, the image storage function, the image distribution function), the following functions: a media browser function, a document browser function, a page browser function, an image process function, a form composition function, a transmission/storage function, an OCR function, a retrieval function, a mail server function, a Web server function, a scheduled execution function, a system monitor function, a security function, a history/condition display function, an individual setting function, an administrator setting function, etc.

The scanner function enables reading an image of a paper original document in a form of an image file and transmitting the image file with email, facsimile transmission, or file transmission using, for example, a Windows share folder system, a Web folder system, FTP software, an external server, etc. The scanner function enables the image file to be stored, for example, in the HDD 17.

The media browser function enables browsing a file stored in the record medium M. Further, the media browser function enables browsing a share folder, an FTP folder, a Web folder, etc. on the network (the LAN 2) in a similar manner as when browsing the record medium M by personally setting the share folder, etc. on the network as a shared virtual medium.

The document browser function enables operating/browsing general documents, images attached to received mails, received facsimile images, etc., stored in the HDD 17. Further, the document browser function includes a document management function, with which names of documents can be changed and documents can be deleted. Furthermore, the document browser function enables retrieving characters in a stored document, which have been recognized in character recognition, and downloading a document from a Web server.

The page browser function enables displaying images in a stored document, a transmitting document, and a printing document. Further, the page browser function enables selecting an image file for printing, transmitting or storing, and browsing and editing various information of a file.

The image process function includes an automatic image process function enabling editing an image before transmitting, storing, or printing the image. The image process function enables correcting image quality, rotating an image, subtracting a color, cutting out an image, deleting a blank, etc.

The form composition function enables generating a new image for transmitting, storing or printing by selecting a form (position information) with a background and by joining a text and/or an image to the selected form. By combining a form generation tool, transmission images and/or print materials can be generated in a wide variety of layouts.

The transmission/storage function enables transmitting image data and/or a file, which has been obtained by scanning a paper original document or selected by media browsing, document browsing or page browsing, to a designated destination by email transmission or facsimile transmission and to a Windows share folder, a FTP server, a Web folder, an external server, etc. by file transmission. Further, the transmission/storage function enables performing character recognition to stored image data to retrieve a character string, and downloading image data and/or a file from a Web server.

The print function enables printing image data and/or a file, which has been selected by media browsing, document browsing or page browsing, while designating a variety of forms and/or layouts.

The OCR function enables extracting a text of a paper original document and/or a received facsimile by performing character recognition to image data of the paper original document and/or image data of the received facsimile. The OCR function includes a function of generating a PDF file by embedding a text obtained by character recognition in an image and to transmit/store the generated PDF file, a retrieval function of retrieving stored image data and facsimile image data by a text obtained by character recognition, and a function of using character strings obtained by character recognition for the address, the document name, the subject, and the body of an email. When a character string obtained by character recognition of a designated area of an original document accords with a registered address, the character string is used for the address, and character strings obtained by character recognition of designated areas of the original document are used for the document name, the subject, and the body of the email.

The retrieval function enables retrieving images and files stored in the apparatus or existing on the network by keywords such as a document name, a file name, a storage date and time, a change date and time, and/or a text obtained by character recognition, and extracting and displaying a file according with the keywords. When retrieving stored image data and facsimile image data by a text obtained by character recognition, character strings obtained by character recognition of image data are covered.

The facsimile function enables receiving facsimile images by facsimile ports provided in the digital color multi-function apparatus 1 (e.g., two G3 facsimile communication ports and one G4 facsimile communication port) as an image file and storing and/or transferring (by way of mail transfer or file transfer) the image file. The transferring addresses of the received facsimiles may be sorted by initial setting according to the originating sources of the received facsimiles and the receiving ports receiving the facsimiles. Further, the facsimile function enables transmitting by facsimile an image file of a paper original document, an image file in a medium, and a stored image file, and transferring an image attached to a received email to another facsimile apparatus.

The mail server function includes a function of transmitting an email, and a function of internally holding a mail address of each individual and a mail address of a guest when setting SMTP (simple mail transfer protocol), automatically printing or transferring by facsimile an image attached to a received email or performing a transmission/storage operation registered to a one-touch button, and returning an email informing of an operation result to the sender.

Here, a combination of operations is provided by default for the mail address of each individual and guest, and setting and changing of the combination of operations can be made in individual setting.

Further, by allocating mail address display names to the mail address of an external mail server when setting POP (post office protocol), an operation substantially the same as one in cases in which SMPT has been set can be realized. To cope with various mail environments, SMPT authentication and POP before SMTP mode can be accommodated with respect to mail transmission, and APOP (authenticated post office protocol) can be accommodated with respect to mail reception.

The web server function enables providing URL (universal resource locators) for each individual and guest, and stored images and files can be browsed, retrieved, downloaded, uploaded, transmitted, stored, and printed. Further, referencing a result of an operation, and setting by an individual setting and administrator setting can be made. Furthermore, to cope with security concerns during communication, SSL server authentication can be accommodated.

The periodic execution function enables deleting stored data past a retention period, receiving POP mails, updating LDAP (lightweight directory access protocol), automatic printing and deleting a history, and automatic rebooting.

The system monitor function enables detecting that a disk is full, that a malfunction has occurred inside the apparatus, that a tray and/or a door have been opened, and that a paper jamming has occurred, and displaying a message, for example, encouraging the user to make a service call. Further, the system monitor function deals with an accounting apparatus monitoring and restricting use by the user.

The security function enables maintaining security of the user operating at the operation panel P, such as authenticating each individual and setting an administrator password, and security of the network, such as authentication of mail transmission, accommodation of APOP, authentication of a SSL server, restriction of access, etc., to protect data from an illegal operation by a guest user and/or an external network.

The history/status display function enables confirming if a result of transmitting, receiving and/or printing an email, a facsimile, and/or a file has been successful, confirming the date and time of execution and completion, confirming execution of canceling a job, and confirming the content of an error that occurred at the time of execution.

The individual setting function enables registering a use environment of each individual user (such as registering mail addresses, customizing screens and operations, setting receiving mail addresses, etc.), individually, without being seen by others. The maximum number of users for which the individual use environment can be set can be 1000.

The administrator setting function enables setting various settings for guest users, setting basic settings for causing respective functions to be operated (such as, setting of the network, setting of time, and setting of automatic booting time), and setting various settings for management (such as setting of user management, setting of the mail environment, and setting of receiving facsimiles).

For realizing the above-described functions, the information process unit B of the digital color multi-function apparatus 1 is provided with, as illustrated in FIG. 6, an individual setting information area allowing registering individual setting information for, e.g., 1000 individuals and an administrator setting information area for registering guest setting information and system setting information.

Next, concrete non-limiting examples of the individual setting information, the guest setting information, and the system setting information, are described. Here, because the content of the guest setting information is substantially the same as the content of the individual setting information, only portions of the guest setting information that are different from those of the individual setting information are described. Further, combinations of information elements and the concrete content of each information element in the following description are only illustrative examples. In describing each information element, the content described in parenthesis indicates an exemplary value that can be applied to the information element and a partial description thereof.

The individual setting information includes, for example as illustrated in FIG. 7A, individual information for identifying each individual, registration information for registering a mail address, etc. for each individual, preset information for registering condition setting information for each individual, individual system setting information for storing initial setting information in using the digital color multi-function apparatus 1, and security information for registering the information relating to security.

The individual information includes, for example as illustrated in FIG. 7B, “kana” (of the name), “name” (in kanji), “position” (indicating a division, a department, etc., to which the individual belongs), “user ID” for identifying each individual, “password” (which is used in authentication), and “sender mail address”.

Here, only names that are unique in the system of the digital color multi-function apparatus 1 can be set for “name”. For example, a character string that represents each user and is used for the title of an individual menu, etc. is used for “name”.

The “user ID” is used when making the transition from a guest menu in the initial setting state to an individual menu. The “user ID” is also used in URL for the individual menu (e.g., http://host name/“user ID”) and in a receiving mail address (e.g., print.“user ID”@host name.domain name).

The “sender mail address” is a character string that is set in the “From” field when sending an email, and is automatically set by default in conjunction with setting of a mail receiving protocol of the administrator setting.

For example, when the mail receiving protocol has been set to POP or APOP, the character string, “name”(of the individual information)[sender.user ID]<POP mail address>, is set by default as the sender mail address.

When the mail receiving protocol has been set to SMTP, the character string, “name”(of the individual information)[sender.user ID]@host name.domain name, is set by default as the sender mail address.

Here, “sender” is the default value of the receiving mail address of “error mail” [01] of the received mailbox (described later). Accordingly, after sending an email, when an error mail has been transferred due to an unknown address, the error mail is stored in “error mail” of the received mailbox.

Each file address includes, as an example illustrated in FIG. 8E, “name” for identifying the file address, “network path” for registering a value of a network path, which is used when transmitting a file to a Windows share folder, a FTP server folder, or an HTTP (an external server) folder on the network, “log-in user name”, “log-in password”, “sub-folder name selection” for registering a sub-folder name which is generated at a host apparatus at the file address, and “communication option designation” for setting whether or not to designate a communication option.

The file address further includes, with respect to “communication option designation” set to designate a communication option, “FTP Japanese mode” for designating the FTP Japanese mode (e.g., a shifted JIS code, an extended UNIX code), “FTP data transfer mode” for designating the FTP data transmission mode (e.g., a PORT mode, a PASV mode), and “OCR address designation”.

Here, “network path” includes, in addition to a network path illustrated in FIG. 9A, a local path illustrated in FIG. 9B.

Here, “external server plug-in” (FIG. 9A) is a function of enabling transfer of a file and designation of a shared media relative to a variety of external servers in a similar manner as in the scheme of FTP and HTTP, without having a sense of difference in the interface. In FIG. 9B, “CompactFlash”, “SmartMedia”, “SD memory card”, and “memory stick” are registered trademarks, respectively.

Each subject/body includes, as an example illustrated in FIG. 9C, “subject” for registering a character string which is used as the subject of an email when transmitting the email and “body” for registering a character string which is used as the body of an email when transmitting the email.

Each document name/user name includes, as an example illustrated in FIG. 9D, “document name” for registering a character string which is used as the document name when storing a document, “OCR” for setting whether or not to perform OCR (optical character recognition), and “user name” for registering a character string which is used as the user name.

The user can make arbitrary settings to the received mailbox [05]-[12].

Here, a unique character string is necessary for “account name” of each received mailbox for each individual setting, and the mail address is set as follows: “display name”<account name=parameter.user ID@identifier.host name.domain name>. Here, the parameter is the telephone number in facsimile transmission and the number of prints in printing. When the parameter of the number of prints is omitted, it indicates that the number of prints is 1. The parameter is not used in file transmission. The SMTP/POP receiving mail addresses that can be actually used are noted on the buttons displayed on a setting/storage screen.

With respect to “transmission/storage”, designation of the transmission/storage form can be made with the transmission/storage condition one-touch, and in this case, the received mails are stored to “general document”. The received mails can be always stored to “received mail” by designation of private mail and by designating the subject as the document name, without designating the password.

With respect to “facsimile transmission”, the facsimile address extracted from the parameter of “To-mail address” is automatically added to the mail address of the designated preset transmission/storage condition.

With respect to “print”, the print form can be designated using the print condition one-touch button.

With respect to “covering letter form designation”, selection is made from forms into which a mail header and a mail body can be inserted. When “covering letter form designation” has been set to perform designating the covering letter form, a designated form is applied only to the mail header and the mail body. When “covering letter form designation” has been designated not to perform designating the covering letter form, a text file form of the basic setting is applied. The text file form of the basic setting is always applied to text files attached to mail.

When “result mail return” has been set to transmit an output result return mail, because an output image can be always browsed on the Web, the output result return mail is transmitted without attaching the output image.

When “received facsimile transfer destination setting” has been set to perform received facsimile transfer destination setting relative to the storage mailbox of the received mailbox, a received facsimile is transferred to the user set as the received facsimile transfer destination at that time.

Here, protection of storage document passwords of guests is realized by setting such that use of the administrator setting password is required when entering from a screen of the main body of the digital color multi-function apparatus 1 or a Web browser and such that the user name of the Web browser is the identification name of the guest setting.

The date/time setting includes, for example as illustrated in FIG. 23E, “date setting” (2003-2099, January-December, 1-31), and “time setting” (0-23 hour, 0-59 minute, 0-59 second).

In communication in which authentication is desired, for example when the other end in the communication is the digital color multi-function apparatus 1, when a URL for obtaining a file is notified to the digital color multi-function apparatus 1 as link information using email, the digital color multi-function apparatus 1 cannot log on a corresponding FTP server (file server) to obtain the file without the user ID and the password for accessing the FTP server.

For avoiding such a situation that the digital color multi-function apparatus 1 cannot log on an FTP server to obtain a file, the user ID and the password required in accessing the FTP server may be included in link information that is notified to the digital color multi-function apparatus 1 using email, which, however, is not desirable from the viewpoint of security because the link information is transmitted without being encrypted.

Therefore, in this embodiment, a confidential link is adopted. That is, the digital color multi-function apparatus 1 is provided with a confidential link information table storing a plurality of pieces of confidential link information as illustrated in FIG. 24A. Each piece of confidential link information includes, as illustrated in FIG. 24B, “address name”, “user ID”, “password”, “schema”, and “network address”.

Generally, the apparatuses exchanging confidential link information with each other often are provided with common confidential link information, and the transmitting end designates the confidential link information to be used by including, for example, “network address/file name” in the body of a transmitting email.

In this case, the receiving end can extract the confidential information link by retrieving the confidential link information table using “network address” included in the received email for the keyword. The receiving end then accesses a corresponding FTP server (file server) using “schema” and “network address” registered in the confidential link information table to obtain a file, and when authentication is requested by the FTP server, the authentication can be met using the user ID and the password. Thus, after logging on the FTP server, by retrieving “file name” of the file, the file can be obtained from the FTP server.

In the digital color multi-function apparatus 1 with the above-described configuration, when the user transmits an image of an original document with email, the address, the subject, and the body of an email described in the image of the original document can be extracted using the OCR function to be automatically set in the email.

Here, as described above, the OCR function is executed at the information process unit B, and for example, commercially available application software compatible with the standard OS installed in the information process unit B can be applied.

In a typical business document, respective parts constituting the document are arranged as illustrated in FIG. 25.

That is, the date is arranged at the upper right part of the document, the address is arranged below the date and at the left side part of the document, the subject is arranged below the address and at the center part of the document, and the sender is arranged below the subject and at the right side part of the document. Further, the season's greeting is arranged, preceding the body of business, and the complimentary close is arranged below the body of business. Further, the postscript is arranged as necessary below the complimentary close.

Generally, in such a business document, respective contents of the date, the address, the subject, the season's greeting, the body of business, the complimentary close, and the postscript change according to the content of the document; however, the construction and arrangement of respective parts of the document need not change and can be applied as a typical form of business documents.

Accordingly, by extracting image data of the areas of the document where the address, the subject, and the body of business are arranged and by applying optical character recognition to the image data, respective contents of the address, the subject, and the body of business of an email can be automatically generated.

In this embodiment, an OCR area information table illustrated in FIG. 26A is provided to the information process unit B. The OCR area information table includes, as illustrated in FIG. 26A, a plurality of pieces of OCR areas information defining reading areas of documents of different types #1 to #m, respectively.

Each OCR area information includes, for example as illustrated in FIG. 26B, an address area table including a plurality pieces of address area information #1 to #k, subject area information, body area information, and optional registration information, which is added as necessary, such as registered address information, registered subject information, and registered body information.

Each area information includes, as illustrated in FIG. 26C, “reference point coordinates” expressing the position of the reference point of the area (the upper left corner of the area), “area width” expressing the size of the area in the horizontal direction, and “area height” expressing the size of the area in the vertical direction.

FIG. 27 illustrates an exemplary scan-to-email process of the digital color multi-function apparatus 1.

First, after setting a transmitting original document on the image read device 8, the user sets a read condition of reading an image of the original document (101), and designates or inputs a mail address, a subject, and a body of an email (102, 103, 104). At this time, suitable guidance screens are displayed, and the user can designate OCR inputting of the mail address, the subject, and/or the body of the email. After completion of inputting the mail address, the subject, and the body, the operation waits until the user instructs to start transmitting the email (105). When the user has instructed to start transmitting the email, the image of the transmitting original document is read with the designated read condition and thereby image data of the image of the transmitting original document is obtained (106).

Then, it is checked whether or not OCR address inputting has been designated in inputting the address (107). When OCR address inputting has been designated (Yes in 107), an OCR address recognition process of obtaining an address based on designated OCR area information is performed (108). When OCR address inputting has not been designated (No in 107), the OCR address recognition process is not performed.

Further, it is checked whether or not OCR subject inputting has been designated in inputting the subject (109). When OCR subject inputting has been designated (Yes in 109), an OCR subject recognition process of obtaining a subject based on designated OCR area information is performed (110). When OCR subject inputting has not been designated (No in 109), the OCR subject recognition process is not performed.

Furthermore, it is checked whether or not OCR body inputting has been designated in inputting the body (111). When OCR body inputting has been designated (Yes in 111), an OCR body recognition process of obtaining a body based on designated OCR area information is performed (112).

When an image process condition has been designated at this time, an image process is executed relative to the image data obtained in step 106 by applying the designated image process condition (113).

Then, header information of the email is generated using the address and the subject that have been obtained (114), and body information of the email is generated using the body that has been obtained and the image data that has been generated in step 113 (115). Generally, the image data is embedded in the body information as an attached file.

The email is then transmitted (116), and the process ends.

FIG. 28 illustrates an example of the OCR address recognition process of step 108.

First, designated OCR area information is obtained (201), one address area information is selected from the address area table of the designated OCR area information (202), an area of the image data obtained by reading the image of the original document is cut off according to the selected address area information and thereby area image data is extracted (203), and a predetermined OCR process is applied to the extracted area image data to obtain a character string (204).

It is then checked whether or not the number of characters recognized by the OCR process (the number of characters in the character string) is equal to or greater than N (for example, N is 8) (step 205), and when the number of characters is equal to or greater than N (Yes in step 205), mail addresses, file addresses, and group addresses registered in association with the user at that time are retrieved by the character string (206).

It is then checked whether or not an address agreeing with the character string has been obtained (207), and when an address agreeing with the character string has been obtained (Yes in step 207), the obtained address is set to address information (208).

Further, it is checked whether or not the OCR process has been applied to all address area information of the address area table of the designated OCR area information (209), and when the OCR process has not been applied to all address area information of the address area table of the designated OCR area information (No in step 209), the process returns to step 202 and the steps 202 through 208 are repeated for the other address area information of the address area table. When the number of characters is not equal to or greater than N (No in step 205) or when an address agreeing with the character string has not been obtained (No in step 207), the process proceeds to step 209.

When the OCR process has been applied to all address area information of the address area table of the designated OCR area information (Yes in step 209), it is checked whether or not the number of addresses obtained by retrieving is zero (210), and when the number of obtained addresses is zero (Yes in step 210), the content of address information registered to the designated OCR area information is set to address information (211), and the process ends. At this time, when no address information is registered to the designated OCR area information, a mail address among mail addresses registered in association with the user, to which OCR address designation has been set, is set to address information. Here, when no address information is registered to the designated OCR area information and no mail address, to which OCR address designation has been set, exists in the mail addresses registered in association with the user, the operation of scan-to-email has failed.

When the number of obtained addresses is not zero (No in step 210), each duplicate address is deleted from the obtained addresses (212), remaining addresses are set to address information (213), and the process ends.

FIG. 29 illustrates an example of the OCR subject recognition process of step 110.

First, designated OCR area information is obtained (301), subject area information is obtained (302), an area of the image data obtained by reading the image of the original document is cut off according to the obtained subject area information and thereby area image data is extracted (303), and the predetermined OCR process is applied to the extracted area image data to obtain a character string (304).

It is checked whether or not the number of characters in the character string is equal to or greater than N (N is, for example, 1) (305), and when the number of characters is equal to or greater than N (Yes in step 305), the character string obtained in step 304 is set to subject information (306).

When the number of characters is not equal to or greater than N (No in step 305), the content of subject information registered to the designated OCR area information at that time is set to subject information (307), and the process ends. At this time, when no subject information is registered to the designated OCR area information, a subject among subjects registered in association with the user, to which OCR subject designation has been set, is set to subject information. Here, when no subject information is registered to the designated OCR area information and when no subject, to which OCR subject designation has been set, exists in the subjects registered in association with the user, the content of the subject is set to be blank.

FIG. 30 illustrates an example of the OCR body recognition process of step 112.

First, designated OCR area information is obtained (401), body area information is obtained (402), an area of the image data obtained by reading the image of the original document is cut off according to the obtained body area information and thereby area image data is extracted (403), and the predetermined OCR process is applied to the extracted area image data to obtain a character string (404).

It is checked whether or not the number of characters in the character string is equal to or greater than N (N is, for example, 1) (405), and when the number of characters is equal to or greater than N (Yes in step 405), the character string obtained in step 404 is set to body information (406).

When the number of characters is not equal to or greater than N (No in step 405), the content of body information registered to the designated OCR area information at that time is set to body information (407), and the process ends. When no body information is registered to the designated OCR area information, the content of the subject is set to be blank.

Thus, according to the above-described embodiment, when the user uses the scan-to-email function in the digital color multi-function apparatus 1, by designating OCR inputting in inputting an address, a subject, and a body of an email, the labor of inputting or selecting the address, the subject, and the body can be saved, which is convenient.

Numerous additional modifications and variations of the present invention are possible in light of the above-teachings. It is therefore to be understood that within the scope of the claims, the present invention can be practiced otherwise than as specifically described herein.
